Compatible with 31 mm festoon sockets and Replacement for 6428 / 6430 / 7065 / DE3021LL / DE3022LL / DE3175LL, these bulbs are designed to refresh small interior and auxiliary light locations in vehicles, RVs, trailers, and 12 V fixtures. Each bulb uses 24 SMD 3014 LEDs arranged around the body to provide wide 360-degree illumination with a clean cool white look that improves visibility in tight spaces. Ideal use cases include courtesy lights, side door lights, glove box lights, vanity mirror lights, step-well lights, luggage compartment lights, and rear reading lights. Installation is plug-and-play in compatible sockets; if a bulb does not light, remove it, rotate 180 degrees, and reinstall due to possible polarity sensitivity.

Some vehicles may require CANBUS-compatible lighting or added resistors to prevent bulb-out warnings, flicker, or dashboard error messages.
